Definitions

  • the present invention concerns a counting process for piled planar substrates, such as sheets, and a device to carry out the process.
  • This patent application discloses a counting disk of a sheet counter for sheets arranged in stack form, in particular notes of value, said rotatable counting disk having circumferential sections which are arranged at regular intervals on the border of said disk and have protrusions projecting in the direction of rotation of the disk, and each circumferential section having a counting opening, a pneumatic counting pulse being triggered when said opening is covered by a sheet, having a suction hollow, whose width and depth increase in the direction counter to the direction of rotation of the disk, and having a group of suction openings which are located one behind the other, are arranged in said suction hollow and can be connected intermittently, via suction ducts, to a negative-pressure source, such that, during operation, the abovementioned circumferential sections leaf through all the sheet corners of a sheet stack one after the other, separate these from one another in the process, under the action of suction and deformation, and cause each sheet to be counted.
  • the abovementioned suction openings are located in the center of the suction hollow, the sections, opening into the suction openings, of the suction ducts are directed essentially perpendicularly with respect to the disk plane and with respect to the base of the suction hollow, and the suction force acts centrally on the suction hollow and perpendicularly with respect to the base of the suction hollow.
  • these counting disks are used on one or two corners of the stack of sheets, thus giving one single counting value or two counting values, e.g. one counting value for each corner.
  • a linear CCD array is used to create a signal representing a high-resolution one-dimensional line scan of the height of a pack that is positioned between stiffening boards used to increase the rigidity of the pack.
  • a compression of the pack is carried out by pressure plate and a piston/clamping assembly before the image is made.
  • the signal corresponding to the image is digitised, stored and then processed by different means (Gaussian filtering, one-dimensional Fast Fourrier Digital Transform etc.).
  • a static two-dimensional CCD array is used to provide a two-dimensional signal and additional signal processing is carried out to translate the signal into a one-dimensional signal along the height of the pack being counted.
  • the two-dimensional CCD array includes rows and columns which are positioned to the pack such that the rows of the array align approximately with the sheets to be counted in the pack. Additional signal processing then averages the values within each row, or samples one column to produce a one-dimensional signal.
  • it is preferred to use a linear CCD array camera also for costs reasons and for speed of processing reasons.
  • an aim of the invention is to provide a counting process that avoids contacting the substrate to be counted.
  • Another aim of the present invention is to provide a process and a system that are able to count piled substrates faster and more accurately than the known process and systems.
  • Another aim of the present invention is to provide a statistical process for counting piled substrates.
  • a further aim of the invention is to detect folded sheets of substrate in a pile.
  • a further aim of the present invention is to provide a device suitable for carrying out the process.
  • Figure 1 shows a general block-diagram of the process according to the invention.
  • Figure 2 shows a block-diagram of a statistical treatment according to the invention.
  • Figure 3 shows the top view of an embodiment of a device suitable for carrying out the process of the invention.
  • the process of the invention is suitable for counting planar substrates, such as sheets of securities or banknotes, checks, cards and other similar objects, piled in a pack and placed in a pouch and comprises the first step of loosening the pack of piled substrates.
  • This loosening is preferably carried out with air under pressure and allows to separate the piled substrates and improve the quality of the counting.
  • the loosening step could be avoided and is therefore optional.
  • imaging means on a counting side of the pack.
  • imaging means will be described further in detail and may include a CCD camera and treatment means.
  • Using a CCD camera allows to form a two-dimensional array of single image detectors, for example pixels, arranged in lines and columns in which one can detect the presence of substrate edges.
  • the image obtained is preferably filtered to remove the noise that is usually present in this type of images.
  • the filtering operation is known per se in the state of the art.
  • each column of single image detectors of the array one then counts the number of sheets of substrates detected in each line of pixel (which have the shape of a segment of line) in order finally to obtain a counting value for each column, said value being the number sheets of substrates detected as segments of lines in each pixel column.
  • CCD arrays have 512x512 pixels, or 1024x1024 pixels or even 2000x2000 pixels, and one will obtain, for example 512 counting values, respectively 1024 or 2000 counting values for the entire array.
  • the set of counting values is then statistically analysed to determine which value is obtained and how often. For example, if the pack of substrate contains theoretically 500 piled sheets of substrates, the correct counting value (500) should appear a certain number of times, for example N 500 times and other counting values such as 499, 498, 497, 501, 502, 503 will also appear a certain number of times, for example N 499 , N 498 , N 497 , N 501 , N 502 , N 503 times.
  • each counting value N cv will appear a certain number of times, the "number of times" being equal to the number of columns in which a counting value is determined.
  • N cv the number of times
  • the most frequently occurring value is accordingly 500, and the other value occurs with the following percentages: 499 0,15%; 498 0,05%; 497 0,25%; 501 0,05%.
  • the predetermined rules may be decided by the user, for example, the relative percentage of the occurrences of the other counting values can be set to a certain limit and if this limit is exceeded, the counting is considered inaccurate.
  • the limit is set at 10%, therefore, if a counting value occurs more than 10% times relatively to the most frequent value, the counting is regarded as inaccurate.
  • the counting value obtained the most frequently is the expected value, and the occurrence of all other obtained values is below the set limit (for example 10% as mentioned above), therefore the counting can be regarded as correct.
  • the counting value obtained the most frequently is the expected value, but the occurrence of one or several other obtained values is over the set limit (for example 10% as mentioned above), and in this case the counting appears correct (the proper value is obtained the most frequently) but should be repeated to check for accuracy.
  • This situation can occur when a sheet is partially folded and is counted on one side of the counting side of the pack, and not on the other side.
  • the counting value obtained the most frequently is not the expected value, and the occurrence of the other obtained values is over or below the set limit (for example 10% as mentioned above).
  • the counting is not correct and the pile has not the proper number of substrates, or a substrate is folded, or the counting is not correct and the counting machine has to be adjusted.
  • this process it is possible to make a second image of the counting side of the pack and then to treat this second image with the process according to the invention described above in order to verify the first counting operation.
  • This second image can be taken and analysed only if the counting operation in the first image has not given the expected result (see second and third case indicated above), or even is the first counting operation has given the correct result, as a verification step of the obtained result.
  • This second image may be taken on the same counting side as the first image, or on another counting side of the pack, with the pack being displaced or not.
  • a key advantage of the process according to the invention is that it is possible to obtain N counting values in one single counting operation, whereas the known counting devices are only able to provide one or two counting values in one counting operation. One can then carry out a proper statistical analysis of N counting values obtained, rather than only compare a maximum of four counting values as obtained with the known devices. With the known devices, it is indeed necessary to carry out N counting operations if one wishes to obtain N counting values.
  • the process according to the invention allows therefore an important saving of time in the counting process and also at the same time a more precise counting process per se with a statistical analysis carried out on high numbers (N counting values) rather than one, two, three or four counting values.
  • packs of planar substrates 1, for example packs of securities or similar objects are brought in front of an imaging device, for example a CCD camera 2, in such a manner that the camera 2 is able to take a picture of a counting side 3 of the pack 1.
  • an imaging device for example a CCD camera 2
  • each pack 1 is surrounded by three walls 4, 5, 6 in order to facilitate the loosening operation which is carried out for example by a jet of air under pressure sent by blowing means 7.
  • This loosening operation thus slightly separates the individual piled substrates and thus improves the quality of the image used for counting.
  • each is placed in a pouch 15 (schematically represented in figure 3) which is open on the counting side of the pack 1. The air used for the loosening operation is therefore trapped in the pouch 15 and the pack remains in a loose configuration.
  • the pouch may be in a synthetic material or paper material, or any other suitable material.
  • illuminating means for example a LED 8 or other equivalent means, which will increase the quality of the image.
  • the CCD camera 2 is linked to a computer device 9, such as a PC or similar device, which comprises at least a microprocessor 10, filtering means 11, input/output interfaces 12 and memory means 13 to store the information.
  • a computer device 9 such as a PC or similar device, which comprises at least a microprocessor 10, filtering means 11, input/output interfaces 12 and memory means 13 to store the information.
  • One of the programs stored in the computer 9 is able to carry out the process according to the invention, in particular by calculating the counting values as defined above and determining their respective frequency.
  • the result of the counting process may then be outputted on an output means 14, for example a computer screen or a printer or even be used to determine the further treatment applied to a specific pile of substrates, for example repeat the counting in case of an inaccurate counting, further processing of the counted pile if the counting operation gives a correct result, specific processing of the counted pile if the counting is not correct etc.
  • an output means 14 for example a computer screen or a printer or even be used to determine the further treatment applied to a specific pile of substrates, for example repeat the counting in case of an inaccurate counting, further processing of the counted pile if the counting operation gives a correct result, specific processing of the counted pile if the counting is not correct etc.
